kelt Posted August 20, 2021 Share Posted August 20, 2021 (edited) Hi all, I am currently doing a trial using the current stable version Unraid 6.9.2. I am not sure if my understanding is correct in this setup: 2 x 2TB disks. 1 to parity and 1 as data disk. Would this be the traditional mirror setup? Supposedly if my data disk fails, I will shutdown the array, replace the disk and do a rebuild from parity? Likewise if my parity disk fails, I will just replace the broken parity disk to be protected again? Many thanks in advance! Edited August 21, 2021 by kelt solved Quote Link to comment

In the special case of 2 drives they happen to be mirrors because of the way parity is calculated. When you expand beyond 2 drives this is no longer true. However the basic process then is still as you describe for a drive failure where you replace the broken drive and the system then rebuilds the parity/data drive to get you protected again. 1 1 Quote Link to comment

kelt Posted August 21, 2021 Author Share Posted August 21, 2021 Thank you all, it works as expected, simulate a disk fail and replaced my disk without any issues. All good! Quote Link to comment
